public class DESedeMac
extends DESMac

This class implements the DES based MAC algorithm as defined in FIPS PUB 113.

This algorithm produces a 4 byte MAC value.

Currently this class will not work correctly unless the input data size is an exact multiple of 8. Data that isnt of this length should be padded with zeros. Eventually the DES cipher class will be modified to perform this function.
